My Best Friend, My Moonlight, Can't Possibly Be the Demon King Hero

[Also known as The Original Novel's Dark Moonlight Male Lead Mistaken for the Genderbent Fanfic's Moonlight Heroine After I Enter the Wrong Book]

Prison Abyss is a novel where every character ends up regretting everything. The heroine is beautiful and kind, yet everyone misunderstands her even though she has done nothing wrong.

They express their love by hurting her, and find a fall guy to provoke her.

Only after the heroine is tortured to death do they learn the truth and finally regret their actions. Consumed by remorse, they tear the fall guy limb from limb, then spare no effort trying to bring the heroine back to life.

Then they kneel before her grave and cry, "We just loved you too much..."

Chen Man's blood pressure shot up as she read. She wanted nothing more than to smash those idiots' heads in. But when she woke up, she had become the fall guy who would eventually be torn limb from limb.

She had no interest in being a sacrificial pawn in their regret-fest. She only wanted to cultivate immortality, and to get the beautiful, kind heroine to work hard alongside her.

"Men don't matter. Besties stick together for life!"

They worked hard together, ate together, slept together, and became the kind of best friends people could only hope to find once in eight lifetimes.

Everything was wonderful.

Until one day, stuck at a cultivation bottleneck and desperate to break through, Chen Man decided to find a cultivation partner for dual cultivation.

On their wedding night.

Her groom lay on the floor, covered in blood. Her best friend wore the bright red wedding robe that should have belonged to him, trapping her between her arms. Pressing her lips close, she smiled tenderly. "Manman, a night of passion is worth a thousand gold pieces. Why are you running?"

Then came the red eyes, the grip on her waist, and the pin against the wall: all three classic moves of a deranged male lead, pulled off in under a minute.

Chen Man: "...???"

Only later, when Chen Man was left weak in the knees every day, did she realize she had been reading a genderbent, all-male-lead fanfic, but had transmigrated into the original novel...

In the original, her gentle, kind-hearted best friend wasn't just genderbent into a man. He was also a ruthless, bloodthirsty, psychologically twisted ultimate demon king who killed everyone in the original until only the title remained!

#Help! Is it still not too late to run?!#

The Abyss is a no-romance novel centered on a male lead, with a tight plot and one thrilling climax after another. Though Jiang Shenyuan is trapped in the mire, he stays true to himself and remains noble and radiant, like an immortal exiled to the mortal world. To his fans, he is the most perfect person imaginable.

The book has one hundred chapters in total, and the clashes between the male lead and the other male characters are especially exciting. The fans have a field day shipping them, until the tone suddenly changes in chapter one hundred.

The book reads:

In the dead of night, the Demon Lord Yuan returned from hell and came back to the mortal world. Facing the people who wept and begged for mercy, he smiled, raised the blade in his hand, and brought it down without hesitation.

One strike, and all were wiped out.

Furious fans wrote countless fanfics in response, the most popular being Prison Abyss, created by the shippers.

A genderbent, all-male-lead fanfic.

He was born a demon seed. Everyone hated and feared him, and even his own parents wished they had never given birth to him.

But so what?

He never cared about love or hate. Their anger and resentment thrilled him, and killing brought him joy.

Then one day, someone said to him, "Don't be afraid. I'll protect you."

A bug he could kill with a single finger said it would protect him... He seemed to have found a more interesting game.

...But what made him seem like a woman?

#He toyed with people's hearts, but later gave everything for just one person's sincerity#

Reader advisory:

1. The heroine makes assumptions from the start and is misled into thinking the male lead is a woman in disguise.

2. One-on-one romance, both leads are each other's first, happy ending.

3. A beautiful-couple pairing. The heroine becomes irresistible to everyone, and is an outrageously over-the-top, chuunibyou Mary Sue.

4. The male lead has almost no moral compass and is equally awful to everyone, but especially awful to the heroine. He's a possessive, unhinged villain.

Theme: Stay true to yourself and press onward with courage.
